NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed. September 2, 1913. Serial No. 787,746.

To all whom it may concern Be it known that l, DENIS Dunner-1r, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Reiillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a non-refillable bottle having improved means for locking the valve mechanism in place and for preventing tampering with the valves.

In the accompanying drawing, Figure 1 shows a bottleneck equipped with my present invention. Fig. 2 is a perspective view of the valve cage and its retaining closure. Figs. 3 and t are cross sectional views on lines 3-8 and ll, respectively, Fig. 1. Fig. 5 is a perspective detail.

Referring to the drawings, 1 designates a bottle, the neck 2 of which is slightly tapered on its inner surface and is provided with a circular shoulder 3 at its base. Within the neck I locate a cage for two ballvalves 4 and 5. This cage is composed of a series of guidebars 6, preferably tour in number, and they bear at their lower ends on shoulder 3, which latter also forms a valve seat with a central opening therein. Within the cage is a saucer-like seat 8 which consists of a flange extending inwardly from and between the guide-bars and having a central opening through which the liquid may flow when the bottle is inverted, but when in its normal position this opening is closed by valve l.

9 is a horizontally-disposed guard located within the cage between valves 4 and 5. It is shown in close proximity to seat 8 and is supported by bars 10 extending from the guide-bars of the cage. There is a narrow space surrounding the edge of this guard to allow of the passage of the liquid, and yet the guard will prevent the inner valve from being tampered with by a rod or wire. While 5 have shown the cage as; termed troma single mold, yet it is to be understood that it may be made in sections.

12 is a closure for sealing the valve mechanism in the bottle-neck, and it comprises inner and outer circular portions with connecting flange 13 for fitting against or over the end of the bottle, the outer portion l l extending around the neck. The latter is preferably formed with longitudinally extending ribs 15 which fit in grooves in the outer portion 14:, the purpose being to prevent the closure from being turned axially. Likewise, the end of the bottle-neck and the inner face of the outer portion 1 1 of the closure are formed with short projections 16 which serve as anchors for the cement or other adhesive agency. For the purpose of hastening the evaporation of the moisture in the cement l: form small openings 17 in flange 13. From the inner end of the inner portion of the closure extends a guard 18 for valve 5, such guard being supported by bars 19. This guard is similar in construction and arrangement to guard 9.

The advantages of my invention will be readily appreciated by those skilled in the art. It will be seen that the valve mechanism is securely positioned within a bottleneck by the closure and that the latter cannot be easily distm-bed; and likewise that by means of the two guards the valves cannot be tampered with. While I have shown and described ball-valves, it will be understood that, if desired, they may be of plug-formation, or otherwise shaped.

I claim as my invention:

In combination with a bottle having its neck pro ided with ribs on its exterior and at its lower end with an interior shoulder forming a seat, valve mechanism in said neck comprising a cage, the lower end of said cage being designed to be supported by said seat, a valve movable in said cage, a closure for retaining said mecl'ianism with in said neck having inner and outer circular portions, inner circular port-ion being designed to bear against the upper end of said cage and having a guard in b to said valve (attending transversi cage with a space surrounding such guard, and said outer circular portion having grooves to accommodate the ribs of the b0ttle neck, and a sealing compound between 5 said outer portion and said neck. In testimony whereof, I have signed this 5 specification in the presence of two subscribing Witnesses.
